Renk's Operations Fire on All Cylinders, but Its Stock Has Stalled 40% Below the Peak

The 4,000th hydro-mechanical gearbox for the Leopard 2 rolled off the line in Augsburg this week — a testament to more than four decades as the tank’s sole drivetrain supplier. Renk used the occasion to confirm development of a next-generation powerpack promising more horsepower and less weight, designed for the future of main battle tanks. Yet the stock, at €51.07, sits roughly 40% below the October 2025 high of €88.73, and the gap between operational achievement and market sentiment has rarely felt wider.

Political headwinds are the principal culprit. Former President Trump’s characterisation of Nato as a “paper tiger” and the spectre of a US withdrawal from the alliance rattled European defence names earlier this year. More concretely, Berlin’s refusal to grant export licences for gearbox systems destined for Israeli armoured vehicles has forced Renk to shift part of its production to the United States. The company is pouring $150m into its Michigan site by 2030, a pragmatic hedge against the very export risks that European policymakers create.

Behind the tariff and treaty noise, the order book is bulging. Renk America booked contracts worth more than $550m last year. For the full group, management targets revenue above €1.5bn in 2026, with adjusted EBIT of €255m to €285m. By 2030, the top line is expected to reach €2.8bn to €3.2bn without relying on acquisitions, while capital expenditure of up to €500m over four to five years will expand capacity and R&D. The defence share of total sales is forecast to climb to around 90% by decade’s end.

Should investors sell immediately? Or is it worth buying Renk?

Investors will look for concrete margin guidance and digital integration plans at Tuesday’s annual general meeting, with the Eurosatory defence exhibition in Paris from 15 June offering another platform to showcase the “NextGen Mobility” strategy. Renk plans to unveil the new ESM 280 gearbox for wheeled vehicles and partnerships in unmanned systems, blending proven mechanical engineering with drive-by-wire technology for autonomous combat platforms.

The stock’s recent behaviour hints at selective buying. After touching a low of €42.12 in mid-May, the share price has rebounded roughly 11% in the past 30 days, and the relative strength index sits at a neutral 50.2. But the annualised 30-day volatility of nearly 50% underscores that this is no sleepy industrial name. The 50-day moving average at €51.50 remains a modest ceiling, and the year-to-date loss stands at 21%.

Renk can deliver the hardware — 4,000 gearboxes for the Leopard 2 alone prove that. What it cannot control are the geopolitical variables that determine whether Europe’s defence budgets stay on their upward trajectory. The upcoming AGM and Eurosatory may provide a catalyst, but the 40% gap to the October high will close only when the political cloud lifts.
